Lone 08-01-2022 02:47 am, 1.  procedure to change the management vlan of aruba 1960 .

Hi, What is the procedure Procedure to change the Management VLAN of Aruba 1960? I had tried by two way:

Way1(DHCP):

1. create new vlan 2 then assign port1 untag and save config 2. change the Management VLAN to 2 and apply. 3. didn't get ip from dhcp server

Way2(static ip) 1. create new vlan 2 then assign port1 untag. 2. set static ip and save. 3. change the Management VLAN to 2 and apply. 4. can't ping the static ip. Any one can tell me what's the procedure to change the Management VLAN? Lone

2.  RE: Procedure to change the Management VLAN of Aruba 1960 ?

Hey Lone, Please look at the configuration guide.

https://www.arubanetworks.com/techdocs/InstantOn_1960_Switch/mcg_1960.pdf

Chapter 4 setup network -> Management VLAN settings, basically add a VLAN and change that as management VLAN when the switch is managed locally.

4.  RE: Procedure to change the Management VLAN of Aruba 1960 ?

Hi JM52, Thank your reply. As Alex Hung reply, I must set not only untag VLAN but also PVID. After setting the untag VLAN and PVID, It's OK. BR., Lone

How to change the management vlan for aruba instant.

Aruba Instant is a very simple and easy to use WLAN solution. In some projects, I have the situation in which users are placed in VLAN 1. Which is easy with Aruba Instant. But unfortunately, VLAN 1 is the default management VLAN and the AP itself should not be placed in VLAN 1. This was impossible in the past but is very easy now. You can change the management VLAN for Aruba Instant and you can use VLAN 1 for your users.

Change the Management VLAN: Untagged on the Uplink In the past, you configured the management IP for the Instant AP. This IP was always in VLAN 1 untagged. This is fine when you do not need VLAN 1 for clients. If you do, you need to have the management IP in a different VLAN. This is possible in Instant for some time now. I did this test with the latest and greatest version available. But the feature is included in Instant since version 4.3.0.

Change the Management VLAN: Tagged on the Uplink Now, let's assume, you need the management VLAN tagged on the uplink. This is possible as well. In the scenario above, I have used VLAN 10 for the management and put this untagged on the uplink.

From the post above you see that it is very simple to change the management VLAN for the IAP and change the untagged VLAN to a different VLAN than VLAN 1.

MAC-based VLANs

MAC-Based VLANs (MBVs) allow multiple clients on a single switch port to receive different untagged VLAN assignments. VLAN assignment of untagged traffic is based on the source MAC address rather than the port. Clients receive their untagged VLAN assignment from the RADIUS server. This feature adheres to the requirement that if all known RADIUS attributes for a given client cannot be applied, the authentication request for that client must be rejected.

Both authenticated and unauthenticated clients can reside on the same port on different VLANs, but only if the mixed-mode configuration is enabled. This is not the default behavior. The normal operating behavior is not to allow unauthenticated clients on the port when at least one authenticated client is present on the port. If an unauthenticated client is present on the unauthorized VLAN and another client successfully authenticates on that port, the unauthenticated client is kicked off the port.

When an MBV cannot be applied due to a conflict with another client on that port, a message indicating VID arbitration error is logged.

When an MBV cannot be applied due to lack of resources, a message indicating lack of resources is logged.

The decision to use an MBV is made automatically if the hardware is capable and if the situation necessitates. If multiple clients authenticate on different untagged VLANs on hardware that does not support MBVs, the switch will reject all clients authorized on a VLAN different from the first client's VLAN - the first authenticated client sets the Port VID (PVID).

This feature has the side effect of allowing egress traffic from one client's VLAN to be accepted by all untagged clients on that port. For example, suppose that clients A and B are both on the same switch port, but on two different VLANs. If client A is subscribing to a multicast stream, then client B also receives that multicast traffic.

Aruba Central with Client Roles and dynamic VLAN assignment

1.  aruba central with client roles and dynamic vlan assignment.

This is both relating to Clearpass and Aruba Central.

When creating a role on Central is not possible without defining a VLAN.

But is that overwritten when using clearpass to assign a Local User Role. as I see it I need to both return the the role and a specific VLAN.

2.  RE: Aruba Central with Client Roles and dynamic VLAN assignment

In the earlier versions of CX, similar to ArubaOS-Switches, the VLAN was defined in the role. Idea behind it (probably) is that you just need to return the role and don't need to bother about VLANs on your RADIUS/ClearPass.

In more recent versions, you now have the option to override the role VLAN (and some other attributes) with RADIUS.

Hope this helps to understand where this is coming from.

3.  RE: Aruba Central with Client Roles and dynamic VLAN assignment

Yes i have allready got it to work.

So now I assign roles where the VLAN and reauth simer is set, and have the client-inactivity timer be the only timer to be set in the LUR, since this apparently cannot be set via RADIUS

Displays VLAN information for an individual port or a group of ports, either cumulatively or on a detailed per-port basis.

Specifies a single port number or a range of ports (for example, a1-a16 ), or all for which to display information.

Displays detailed VLAN membership information on a per-port basis.

The following describes the fields displayed by the command (see example output):

The user-specified port name, if one has been assigned.

The VLAN identification number, or VID.

The default or specified name assigned to the VLAN. For a static VLAN, the default name consists of VLAN-x where x matches the VID assigned to that VLAN. For a dynamic VLAN, the name consists of GVRP_x where x matches the applicable VID.

Port-Based, static VLAN.

Protocol-Based, static VLAN.

Port-Based, temporary VLAN learned through GVRP.

Indicates whether a port-based VLAN is configured as a voice VLAN.

Indicates whether a VLAN is configured for jumbo packets. For more on jumbos, see "Port Traffic Controls" in the management and configuration guide for your switch.

The Aruba switches support the following types of VLANs Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. :

Port-based VLANs—In the case of trusted interfaces, all untagged traffic is assigned a VLAN based on the incoming port.

Tag-based VLANs—In the case of trusted interfaces, all tagged traffic is assigned a VLAN based on the incoming tag.

The Aruba Mobility Access Switch also supports the following types of VLANs:

Voice VLANs—You can use voice VLANs to separate voice traffic from data traffic when the voice and data traffic are carried over the same Ethernet Ethernet is a network protocol for data transmission over LAN. link.

MAC Media Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. -based VLANs—In the case of untrusted interfaces, you can associate a client to a VLAN based on the source MAC of the packet. Based on the MAC, you can assign a role to the user after authentication.

Adding VLAN Details

By default, all ports in the Switches are assigned to VLAN 1. However, if the ports are assigned to different VLANs, the VLANs page displays their details.

To add a VLAN, complete the following steps:

1. In the Network Operations app, select one of the following options:

To select a switch group in the filter:

a. Set the filter to a group containing at least one switch.

The dashboard context for the group is displayed.

b. Under Manage , click Devices > Switches .

c. Click the Config icon to view the switch configuration dashboard.

To select a switch in the filter:

a. Set the filter to Global or a group containing at least one switch.

A list of switches is displayed in the List view.

c. Click a switch under Device Name .

b. Select any of the following port modes:

Tagged Ports

Untagged Ports

5. To assign the VLAN to a trunk group, select the trunk group in the Trunk Groups table.

6. Click OK .

7. Click Save Settings .

Editing the VLAN Details

To edit the details of a VLAN, point to the row for the VLAN, and click the edit icon in the Actions column, and configure the parameters.

Deleting VLAN Details

To delete the VLAN details, complete the following steps:

1. Ensure that the VLANs are not tagged to any ports.

2. Point to the row for the VLAN, and click the edit icon in the Actions column.

Configuring DHCP Relay Settings

You can configure a switch as a DHCP relay agent for transmitting DHCP messages between the DHCP server and client. You can also configure the option-82 feature for the switch to include DHCP relay information in the forwarded DHCP request messages.

To configure a switch as a DHCP relay agent, complete the following steps:

3. Expand the DHCP Relay Settings accordion.

4. To enable DHCP relay, move the DHCP Relay toggle switch to the on position.

5. To enable option-82 feature, move the DHCP Relay Option 82 toggle switch to the on position.

6. Click Save Settings .

IP and Network Assignment

The IP and network assignment setting in the Aruba Instant On mobile app allows you to configure internal/external DHCP and NAT for clients on employee networks or guest networks. You can configure one of the following settings on your device:

• Same as local network (default) —This setting is referred to as Bridged mode . Clients will receive an IP address provided by a DHCP service on your local network. By default, the default network created during setup is assigned as your local network. To assign other networks, select the network from the Assigned network drop-down. The VLAN ID will be assigned to your network based on your network assignment. This option is enabled by default for employee networks.
• Specific to this wireless network —This setting is referred to as NAT mode . Clients will receive an IP address provided by your Instant On devices. Enter the Base IP address of the Instant On AP and select the client threshold from the Subnet mask drop-down list. This option is enabled by default for guest networks.
